Parser rejects i32.reinterpret/f32

[sunfishcode]

For this code:

(assert_eq
  (i32.reinterpret/f32 (f32.const 1.0))
  (i32.reinterpret/f32 (f32.const 1.0))
)

wasm says:

test/test.wasm:2.4-2.23: syntax error

As far as I can tell, i32.reinterpret/f32 should be a valid opcode recognized by the lexer. Is this code actually invalid, or is there a parsing bug here?

The error is with your use of assert_eq: it only allows an invoke on the LHS, not a naked wasm expression.

Ah, got it. I was attempting to write floating point tests that test for specific bit patterns, since assert_eq just uses <>. It looks like the solution is new flavors of assert then.
